cfc874ee52 Open the store before constructing EvalState. 
EvalState requires the `store` global to be initialized before it is constructed
in some cases, e.g. when it needs to download a tarball for something in
NIX_PATH. Hence, this fixes #13.

According to popular practice and convention `nix-repl` now supports `--help`
like a good POSIX citizen[1].

3c67df928f Add sugar for defining a variable 
‘x = <expr>’ is short for ‘:a { x = <expr>; }’.  Note that the
right-hand side refers to the original scope, so you get:

  nix-repl> x = 1
  nix-repl> x = x + 1
  nix-repl> x
  2

rather than an infinite recursion.

Example:

$ nix-repl '<nixos>'

> config.services.xserver.desktop<TAB>

comletes to

config.services.xserver.desktopManager.kde4.enable
config.services.xserver.desktopManager.kde4.phononBackends

7e3625f924 Improved value display 
By default, we don't recurse into attribute sets or lists when
printing a value.  However, the new :p command does recurse.

However, this may leave thunks in black-holed state, so it's not
really safe.

the resulting attribute set to the interpreter scope.  For instance:

nix-repl> lib.range 0 10
[ 0 1 2 3 4 5 6 7 8 9 10 ]
